CVE-2026-54660

swagger-typescript-api generates API clients for Fetch or Axios from OpenAPI specifications. Prior to 13.12.2, src/resolved-swagger-schema.ts getRemoteRequestHeaders forwards --authorizationToken to every URL fetched by fetchRemoteSchemaDocument while warmUpRemoteSchemasCache resolves external $ref URLs, allowing an attacker-controlled OpenAPI spec to exfiltrate the developer or CI bearer token to a cross-origin endpoint. This issue is fixed in version 13.12.2.

Summary		(es) swagger-typescript-api genera clientes API para Fetch o Axios a partir de especificaciones OpenAPI. Antes de la versión 13.12.2, src/resolved-swagger-schema.ts getRemoteRequestHeaders reenvía --authorizationToken a cada URL obtenida por fetchRemoteSchemaDocument mientras warmUpRemoteSchemasCache resuelve URLs $ref externas, permitiendo que una especificación OpenAPI controlada por un atacante exfiltre el token portador del desarrollador o de CI a un endpoint de origen cruzado. Este problema está solucionado en la versión 13.12.2.
